Sorry if this has been asked/answered before, but I"ve tried every combination I can think of to search & haven't come up with anything relevant yet.

My 12" powerbook seems to run kind of hot. Today it registered 140 Degrees F. The fan also runs pretty much every time I use it. Many times the fan will start running, then I'll go away & when I come back, the screen has dimmed, no apps appear to be running (that I can tell) & yet the fan is still on.

Today, I ran the "Activity Monitor" application & saw that my CPU system useage is almost always at 100%, with the system using between 14-40% of the CPU, with the rest going to "user". When I scroll through the apps, Activity Monitor is using 10-11% of the CPU, Palm Desktop is using .5% and every other app registers 0%. Am I missing something, or doing something wrong?

Thanks in advance for any help you can offer.

OK, I found a thread about temps, so that's all good. But I'm still perplexed as to why the CPU useage is at 100% all the time. The system uses 15-40" of the CPU, apps use about 10-15%, but the rest seems to be unaccounted for. Any ideas on that?

Hi,

In activity monitor utility, open the activity monitor window and then click on the "% cpu" header to sort by cpu useage (be sure the pop-up menu is set to show "all processes"). Then you should be able to see what app or process is hogging the cpu.

Also check out Temperature monitor 3.4 which displays multiple temperature monitors as well as specific normal ranges for your model:

Thanks, I'll give it a try. The problem I was having is that I don't see any app that is taking up much of the processor. I'll see if this roots out the problem.
